Abstract

This project is a hand shovel. It can also be scaled up easily into a normal shovel. This fulfills a need where people need a shovel or don't have normal access to the materials.

Bill of Materials

Tools needed for fabrication of the OSAT

MOST Delta RepRap or similar RepRap 3-D printer
A 2 part epoxy or other adhesive

Technical Specifications and Assembly Instructions

Print at least one shovel and one handle. Handles fit together. It is recommended to print 2 handles to allow for a nice grip room.

The shovel can take 5+ hours to print. Each handle can take 1+ hour to print.

Assembly

Expect assembly to take 1-2 hours depending on your adhesive.

Step 1 - Remove any extra plastic from the printed holes.
Step 2 - Glue pieces together

Common Problems and Solutions

One common problem is making is inset hole to small for the handle. Make sure that you make the inset hole at least 1 mm bigger.

Cost savings

Total build cost with 2 handles - $3.80

$4.68 - $3.80 = $0.88

Based on the developmental needs addressed (e.g. food, heat, electricity, clean water, health care, etc.) be sure to label your device in the proper categories e.g. use [[Category:Water]]. Be sure to categorize your device so that it will be easy to find – for example “Low voltage connection basics” is categorized in
